Rapid social-economic development and the ever-increasing water pollutant discharge of Wuliangsuhai lake basin made the water quality deteriorated; the lake eutrophication intensified and heavily restricted the sustainable development of the watershed’s social economy. Wuliangsuhai lake basin was selected as the study area. By the use of system dynamics simulation model the water environment and social economy were connected, and three kinds of improved scenarios (resource-environment constrained type, social economy constrained type, coordinated development type) were proposed based on the inertial and planning schemes. Ten indexes of water environment carrying capacity, i.e. the GDP per capita, ratio of industrial output to GDP, et al., were selected, and fuzzy comprehensive evaluation method was used. Results showed that, the water environmental capacity utilization ratios of COD and TN in the resource-environment constrained scenario were 69.5% and 57.9% in 2020, respectively. And the water environment carrying capacity index increased from 0.19 in 2008 to 0.31 in 2020. Under the coordinated development scenario, the surplus environmental capacity of COD and TN were 1755.46t/a, 260.21t/a respectively, and the water environment carrying capacity index was up to 0.29 in 2020. The sustainable development plan was proposed and some feasible suggestions and strategies were put forward.

Crop Waste

The increase in the need for animal-based food consumption creates opportunities in the development of cattle farming in the future. But the problems in the field are a decrease in livestock productivity such as a decrease in livestock population and a decrease in livestock body weight, this is due to the lack of availability of sustainable animal feed. The solution offered is to use food crop waste as an alternative feed for livestock, so it is necessary to analyze the carrying capacity of food crop waste in an area. The purpose of this research is to analyze the potential resources of beef cattle feed based on food plant waste in West Sumatra Province and to analyze the nutritional content of food plant waste. The research was conducted in West Sumatra Province in January 2021. The method used was literature study and secondary data analysis. The data required consists of: (1) food crop production data, (2) beef cattle population data in West Sumatra Province. Data were analyzed by analyzing the carrying capacity of food plant waste. The results showed the availability of feed in West Sumatra Province 728,195.32 tonnes BKC / year, while the current total feed requirement is only 410,159.32 tonnes BKC / year. This shows the large potential for feed that has not been utilized, and this means that there is a large opportunity for Prov. West Sumatra in the future development of ruminants. The carrying capacity index of food plant waste (IDD) is 2.37, which means that it has a safe status where food plant waste is able to help support the needs of animal feed in West Sumatra Province. To increase the nutritional value of food plant waste, it can be overcome by giving a touch of waste processing technology innovations such as fermentation, silage, or ammonia. The results of this study are important as recommendations for the government regarding the sources of information on areas that have the potential to develop livestock business, which can be seen from the status of the area’s carrying capacity index or the potential availability of abundant animal feed.

The rapid development of urbanization, population growth, and unreasonable use of land resources have made the contradiction between human beings and land increasingly prominent, and the carrying capacity of land resources has become an important factor affecting the sustainable development of a city or even a country. Based on the carrying capacity of agricultural land, construction land, and ecological land in 31 provinces of China, this paper analyzed the spatiotemporal characteristics of the carrying capacity of land resources in 31 provinces of China from 2008 to 2016 by using single-factor carrying capacity evaluation and comprehensive carrying capacity evaluation methods. The evaluation results were divided into six levels (No pressure, Lower pressure, Low pressure, Medium pressure, High pressure, Higher pressure), and the ArcGIS10.2 software was used for visualization, and the carrying capacity prediction model was constructed to predict the development trend of the comprehensive carrying capacity of land resources in 2020 and 2025. The results showed that China’s land carrying capacity is extremely unbalanced. Whether from the evaluation results of single-factor carrying capacity or comprehensive carrying capacity, we showed the characteristics of high pressure in the east and low pressure in the west, and that the regional land resources have a deteriorating trend. Through the prediction of the future land resource carrying capacity index, it was found that the comprehensive carrying capacity index of land resources in 31 provinces of China will still show an upward trend in the future.

This study aimed to analyze the potential for cattle business development in Indramayu Regency. The research locations selected using purposive sampling method were based on the following criteria: (1) Indramayu Regency is the 2nd largest rice producers in the Province of West Java, (2) The area covers 2,099.42 km2 based on secondary data obtained from BPS Indramayu Regency in numbers and (3) The area of agricultural land is still larger than the area of resident housing. The data analysis method used the carrying capacity index (IDD) and Location Question (LQ) analysis formulas. The data were processed and explained descriptively. The results of this study resulted in carrying capacity values consisting of 3 patterns, namely the highest carrying capacity value > 20,000 AU (Gantar and Terisi). Medium carrying capacity value > 10,000 AU (Cikedung and Gabuswetan). Low value carrying capacity 5.000-10.000 AU (Haurgelis, Suyeg, Juntiyuat, Bongdua, Kertasemaya, Patrol, Kedokanbunder and Sindang). The results of the analysis of IDD > 2 there are 12 sub-districts, meaning that based on the availability of forage feed from agricultural land, it is included in the safe category to increase the population of beef cattle. The potential for beef cattle development in Indramayu Regency needs to be prioritized in 12 sub-districts with LQ > 1 and IDD > 2 accompanied by government policies to support investment in livestock marketing facilities and infrastructure for smallholders.
